对于高分辨率光谱学、光化学、冷却/捕获和光学遥感等激光应用，准确的波长信息至关重要。然而，可调谐激光器和激光二极管的确切波长是未知的。因此，有必要对激光波长进行测量，以确保获得最有意义的实验结果。确定连续波激光器绝对波长的最佳方法是使用布里斯托尔仪器公司的621激光波长计。该系统提供实时激光波长信息，其精度由连续测量保证
For laser applications such as high-resolution spectroscopy, photochemistry, cooling/trapping, and optical remote sensing, accurate wavelength information is critical. However, the exact wavelength of tunable lasers and laser diodes is not known a priori. Therefore, it is necessary to meas ure laser wavelength to ensure the most meaningful experimental results. The best way to determine the absolute wavelength of CW lasers is with the 621 Laser Wavelength Meter from Bristol Instruments. This system provides real-time laser wavelength information with an accuracy that is guaranteed by continuous calibration with a built-in wavelength standard. The result is the reliable accuracy that is required for the most demanding applications.
